TRACTOR-BINDER HITCH.

Specification of Letters Patent.

Fntented Nov. 3,

To all whom 'it may concern.'

Be it known that I, CnanLi-:s Pearson', a citizen of the TJnited States, residing at Chicago, in the county of Cook and State of Illinois. have invented certain new and usefiil Improvements in rractcr Binder Hitches, of which the following 'is a full. clear` and exact specification.

My invention relates to draft mechanism whereby a series of grain harvesters or other implements may be connected together in tandem relation and drawn forward` by a single source of power, as traction engine, to which the forward machine of the series is connected, and consists in providing improved draft connections between the (liderent units and between the series and the source of power that may be manipulated b v the operator upon the machine .in an improved manner to control the line of advance of one machine independent of the. others,l

whereby a greater or less width of swath may be cut by either unit of the series, or the machines may be controlled in a manner to trail one directly behind the other, or at any desired degree of offset relation.

The object of my invention is to provide an improved draft mechanism of the character indicated that may be readily controlled in a simple and positive manner for the purpose described, and which is strong in construction and etlicient in operation.

l attain these objects by means of mechanism, one embodiment of which is illustrated in the accompanying drawings, in which- `Figure l represents a top plan view of my invention as applied to the frame of a harvester; Fig. 2 is a side elevation of Fig. l; Fig. 3 is a top plan View on a reduced scale of the mechanism and is designed to illustrate the manner of connecting a plurality of harvesters in tandem relation; Fig, i is an enlarged front elevation of part of the controlling mechanism along line A-li of Fig. l; Fig. 5 shows a modified form of the invention having the draft member secured to the harvester frame directly; and Fig. G is 1n end elevation of Fig. v

The same reference numerals designate ike parts throughout the several views.

l represents the grain platform of a har- 'ester, including a front frame member 2 vnd a rear meinbeif; 4 represents the front .lember of the wheeled frame having the rainward end thereof secured to the meinber 2; 5 the rear member of the wheeled frame having the gra inward end thereof secured to the rear member 3 of the grain platform. A

2T represents a yoke member" mounted upon the rear end of shaft 23,and in which is journa'led the lower end of a vertically arranged shaft 28, having secured thereto Va bevel pinion 29 engaging with .the gear wheel 26, the .upper end of said shaft being journaledin a bracket member 30 secured to the harvester frame and having integral therewithfa crank member 31 Within convenient reach of the operator, whereby the angular relation of the draft tongue and harvester `may` be readily controlled by a manipulation of the shafts 23 and 23, the worm 20, the segmental wheel 18 and the connecting linkl). Y

32' represents a supplemental Wheeled frame member having the forward end' thereof secured to the frame member 7 and extending.rearward and grainward has the rear end thereof secured to the rear members 3 and 5 of thegrain platform and wheeled frame, respectively, and represents a simirear end thereof secured to the wheeled frame member 7 and.

' extending forward and grainward has the forward end secured to the front members 2 J and 4' of the grain platform and wheeled frame, respectively, the function of the members 32 andA 33 being to resistl a tendency of the draft force to distort the Wheeled frame and the. grain platform.

For the purpose of giving additional strength toV the wheeled frame and grain platform of the harvester, I have provided a supplemental frame member 34 having the front end thereof secured to the wheeled frame member 7 in a vertical plane with the axis of the traction wheel through the bracket member 14, and extending rearward and grainward has the opposite end thereof secured to the rear framemember 3 of the grain platform by means of a bolt 35, and 3G represents an additional frame strengthening member preferablyy arranged parallel with the wheeled frame member 7 and having-the front end thereof secured to the Wheeled frame member 7 in a vertical plane with the axis of the traction wheel through bracket membe 14, and the body portion thereof rigidly secured tQ the harvester frameV by `meansvof a clip member 37, the gear end 'of the member V,36 beine` turned downward beyond the. clip and lprovided with a verticallyarranged opening that receives a bolt 38 whereby said frame member is rigidly secured-to the stubbleward end of a draft bar 39, the 'oppositeend of'said bar being secured to the rear member 3 of the grain platform preferably by means ofthe bolt 35, and the body of the bar arranged concentric to the axis of the pivotal vconnection of the draft tongue with the bracket member 91. The bar. 39 maybe secured to the Wheeled frame and grain platform inshown in Figs. 5 and 6, if desired; the prin- .cipal function of the bar '36 being to permit 39 to be readily attached to various thebar l designs of harvester frames. In the construction shown in Figs; 5 and 6, the bar 39 is attached to the frame members 5 and 7 by means of the brackets 391. 40 represents a draft clevis having th'e rear end thereof pivotally connected With the front end ,of the draft tongue 11 by means of a bolt 41, and 42 represents a sheave journaled upon a vertically arranged bolt 43 at the front end' of the draft clevis whereby thedraft tongue is operatively connected with the dra'ft bar 39 in a manner to swing freely thereon as controlled by the tongue adjusting mechanism and the draft force applied to the machine. i

In operation a plurality of .harvesters oil other implements are arranged in tandem relation, as illustrated by Fig. 3 of the drawings, and the draft tongue adjusting mechanism may be manipulated in a manner to canse the machines of the series to assume more or less of an offset relation relative to each other and `with the source of traction power, or they may be arranged in a manner to trail in substantially the same path, as

when being transported from field to-,field or upon the road, the connection of the front` end of each draft tongue with the machine infront thereof being entirely independent of the connection of the rear' end of the draft tongue of the forward machine; the connection of the front ends of the tivo sup! plemental frame members 34 and 36 being near 4the axis of .the traction Wheel, any liability of the wheel frame becoming distorted by reason of the draft being carried solely by the harvester frame is eliminated.

Vhile I have in this application described certain embodiments of my invention, it is,

of course, to be' understood that the forms` chosen are used for purposes of illustration,

and that the invention itself may be embodied in other forms and modified Without departing from its spirit;

`YVhat I,claim as'mv invention and desire to ser-.ure b v Letters Patent is:
